A little story.
I was sitting on the train from Plymouth to Truro yesterday and there was a young couple having one of those play-fight bickering contests all the way to Bodmin Parkway where they got off.
They were having a whale of a time to themselves, poking fun and trying to embarrass each other.
I reckon he won, though.
Just as the train pulled into Bodmin and they were about to alight he said, loud enough for most of the carriage to hear,
"Just remember, I've seen you naked. And you've got a dimple on your bum."
She blushed beautifully.
